First fight for base and found issues for both my suggestions and current update:
Shield autooff + delay for it to get on + synced attacks = 36k repairs resources per 10 hours at lvl1 and 1/3 repairs only. It only has chance with all storage modules on it or all weapon modules, as in a radius - even 4 weapon platforms wont cover you from long range novas and HMs.
It's better to suply base with shield on for a long time then to ship 90k of repairs + 20k of fuel + somek of crew suply every single day.
Or... At least... shield could never go off faster then 10-20 minutes. Or other player specified time and... should be turnable into ON to stay so untill turned off manualy
AND + it must ignore friendly/ignored fire for hostality and ability to accept tags in the end of charname, just like activity counter. As now 1 shot and base turns against it's owner even if he relogs. Some told me base gets bugged at 20 tag - so we can't just fill the list with all names faction has.
